I'd consider
you the "big jerk head" for bidding on an auction that
clearly stated up to 30 days to ship, then trying to get the seller in trouble for sticking to those terms.
You sound like the jerks whining about high shipping & handling charges that were also clearly stated.
If you don't like the terms of an auction,
don't bid on it.
He is not selling preorders, he is selling an item. An item he doesn't have
If he is unable to ship the item on time then you have a point, otherwise not much of one.
